Read values from localized file iOS

Question

I have created a localized string file which contains Error message in Key/Value Pair. What I just want to read values on key basis just like Plist.

Here is content of my Localized file

"SERVICE_ERROR" = "Some error occurred while processing your request, Please try later";

And this is how I am saving this string in user preferences

[ErrorManager setLastErrorInPreferences:NSLocalizedString(@"SERVICE_ERROR", nil)];

Here is setLastErrorInPreferences method

+ (void)setLastErrorInPreferences:(id)errorString {
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSDate *now = [NSDate date];
    NSString *errorStringWithTime = [NSString stringWithFormat:@"On %@:\n%@", now, errorString];
    [prefs setObject:errorStringWithTime forKey:KlastError];
}  

But its not working. Its just saving the key as it is. Its not reflecting the value of this key in user preferences.Kindly let me know what I am missing.

Answer 1

I am assuming you have a Localizable.strings file. No other name will work.
Change the content of your localizable file from

"SERVICE_ERROR" = "Some error occurred while processing your request, Please try later";

to

SERVICE_ERROR = "Some error occurred while processing your request, Please try later";

(Remove "" from your key SERVICE_ERROR and keep a semi-colon at the end ;)

Also show what your setLastErrorInPreferences is doing?

Usage

NSString* error = NSLocalizedString(@"SERVICE_ERROR", nil);   
NSLog(@"%@",error);

It worked fine.

My File

EDIT

Fetching the errorValue. Make some method in your ErrorManager class and fetch it from there as kLastError won't be available in your Controller class.

NSString* yourError = [[NSUserDefaults standardUserDefaults] stringForKey:KlastError];
